PCIe Slot determination
The PXH840 supports PCIe Gen1, Gen2 and Gen3 speeds and x1, x2, x4, x8 and x16 link-widths. The slot width and speed will affect
the performance of the card. The card can be physically installed in an x4, x8 or x16 connector. The card will auto configure to the
slot speed and width.
• Install the board in a slot connecting directly to the CPU for optimal shared memory performance.
• Install the board behind a PCIe switch in the IO system for optimal PCIe peer to peer performance (e.g. between GPUs,
FPGAs)
TIP: After installing the eXpressWare software, run the “sisci_benchmarks” benchmark suite to verify the expected performance.
Please contact Dolphin support if you need assistance to reach the expected performance.
PXH840 Configuration
The PXH840 has a DIP switch bank to control the main configuration of the card. The DIP switch labeled SW1 can be found close to
the upper edge of the board. The default DIP switch setting is single NTB link x16 operations. Alternative NTB configuration settings
is two x8 links. The PXH840 also supports Transparent configuraitons, the alternatives are one, dual or quad IO Expansion.
Operating environment
To maximize life time for the product and maintain the warranty, please honor the specified operating temperature and make sure
the specified air flow is present. Special care should be considered when PXH840 is used in office type cabinets in combination with
other high energy consuming PCIe devices, e.g. not active cooled GPUs:
Operating Temperature: 0°C - 55°C (32°F - 131°F), Air Flow: 150 LFM
Operating Temperature with AOC: 0°C - 45°C (32°F - 113°F), Air Flow: 150 LFM
Relative Humidity: 5% - 95% (non- condensing)
TIP: After installing the Dolphin eXpressWare software, you can use the tool dis_diag to determine the actual board temperatures.
Cable Connections
The PXH840 is designed for Samtec FireFly optical engines. The card support any length up to 100 meters without any special PCIe
tuning.

Installation
Step 1 - Unpack board
The PXH840 card is shipped in an anti-static bag to prevent static electricity damage. The card should only be removed from the
bag after ensuring that anti-static precautions are taken. Static electricity from your clothes or work environment can
damage your PCI Express adapter card or your PC. Always wear a grounded anti-static wrist strap while opening the
PC and when the PXH840 is removed from the anti-static bag.
Step 3 - Configure the board for proper operation
The PXH840 board support both NTB and Transparent use-cases and must be configured using the DIP Switch to meet your specific
use case.
NTB Configuration settings
DIP switch settings for the NTB use cases, two node x16 or three node x8. These settings must be applied to all cards in the PCIe
network.

Table 1: PXH840 SW1 NTB configuration settings.
Step 4 - Install the Adapter Card
Before installing the adapter card, make sure you are properly grounded to avoid static discharges that may destroy your computer
or the adapter card. Ensure you are properly grounded before opening your computer or the anti-static bag
containing the PXH840. Please follow your computer’s or expansion chassis manual on how to install a PCI Express
card.
The PXH840 Adapter card can be installed into any PCI Express x16 slot. The PXH840 supports PCI Express Gen1,
Gen2 and Gen3 signaling. NOTE: A Gen3 slot is recommended as it typically doubles the performance compared to a Gen2
slot. The PXH840 is an x16 card, so maximum performance will only be attained if the slot provides full electrical x16
signaling.
The PXH840 supports hosts using either spread spectrum or constant frequency clocking. The card implements clock isolation.
Step 5 - Installing and Removing Cables
Installing and removing cables in NTB mode can be done while the systems are running. Hot plugging / removing cables are fully
supported. In transparent mode, hot plugging and replacing cabels are normally not supported.
Connecting Cables
Please carefully install the fiber patch cable connector into the connector housing on the PXH840 adapter card. To install the cable,
match the cable house color with the MTP connector on the PXH840 adapter card. Use even pressure to insert the connector until
it is secure. Computer cables should always use strain relief to protect the connected equipment from excessive force on the cable.
This is especially important for cables between racks.
Disconnecting Cables
Please carefully pull the release tab to release the cable from the locking latches and gently pull the cable out of the connector
guides.
